Evaporation of Solutions

Key Stage 2

Evaporation of a solution is a way to get back a solid that has been dissolved in a liquid.

When you heat a solution the liquid will evaporate leaving the solid behind.

	You can separate salt from the water by evaporating the water in an evaporating dish.


These people collect salt by putting sea water in small ponds and allowing the warm temperatures to evaporate the water away leaving the behind the salt.

Evaporation of a solution is a way to recover the solute that has been dissolved in a solvent.

The evaporation of solutions recovers the solutes but loses the solvent.

Evaporation of solutions can be done by directly heating the solution or by giving time for the liquid to evaporate at low temperatures.
